Problems solved by technology

[0003] In recent years, there are many planting methods, and the "greenhouse planting method" is widely used at present. This method is concentrated planting, easy to manage, high in output, and good in economic benefits. However, building a greenhouse scaffolding requires a large one-time investment cost. In the process, the growth environment conditions of Dendrobium must be strictly controlled to shorten its growth cycle, and the stems are thick and plump. Some farmers even over-use pesticides and fertilizers to increase production. The result of the synergy of various factors makes the production of Dendrobium officinale Although it is high, its internal quality is far worse than that of wild dendrobium, and its medical and health effects are also greatly reduced.

Embodiment 1

[0025]Soak the carrot seeds in salt water with a mass concentration of 10% and dry them in the air, crush them at 18 degrees Celsius and pass through a 100 sieve, then mix the powder with petroleum ether at a volume ratio of 1:3 and put it into a Soxhlet extractor Soak for 10 hours, and use a microwave power of 400MHz for 20 seconds after every 2 hours. After soaking for 10 hours, reflux extraction at 70 degrees Celsius for 5 hours. Ultrasonic assisted extraction is performed during the reflux extraction. The frequency of the ultrasonic wave is 300W. Reflux extraction After the completion, the petroleum ether extract can be obtained, and then the petroleum ether is recovered through a rotary evaporator to remove water to obtain an oily liquid, which is placed in a drying oven under a vacuum degree of 1.2 standard atmospheric pressure to constant weight, and the mountain carrot seed oil can be obtained; Carrot seed oil contains 22% fatty acids.

Embodiment 2

[0027] Soak the carrot seeds in salt water with a mass concentration of 15%, dry them, crush them at 18 degrees Celsius and pass through a 100 sieve, then mix the powder with petroleum ether at a volume ratio of 1:8 and put it into a Soxhlet extractor Soak for 10 hours, and use a microwave power of 500MHz for 30 seconds after every 2 hours. After soaking for 10 hours, reflux extraction at 70 degrees Celsius for 6 hours. Ultrasonic assisted extraction is performed during the reflux extraction. The frequency of the ultrasonic wave is 500W. Reflux extraction After the completion, the petroleum ether extract can be obtained, and then the petroleum ether is recovered through a rotary evaporator to remove water to obtain an oily liquid, which is placed in a drying box under a vacuum of 1.5 standard atmospheric pressure to constant weight, and the mountain carrot seed oil can be obtained; Carrot seed oil contains 28% fatty acids.

Embodiment 3

[0029] Soak the carrot seeds in saline with a mass concentration of 12%, dry them, crush them at 18 degrees Celsius and pass through a 100 sieve, then mix the powder with petroleum ether at a volume ratio of 1:5 and put it into a Soxhlet extractor Soak for 10 hours, and use a microwave power of 450MHz for 25 seconds at intervals of 2 hours. After soaking for 10 hours, reflux extraction at 70 degrees Celsius for 5.5 hours. Ultrasonic assisted extraction is performed during the reflux extraction. The frequency of the ultrasonic wave is 400W. Reflux extraction After the completion, the petroleum ether extract can be obtained, and then the petroleum ether is recovered through a rotary evaporator to remove water to obtain an oily liquid, which is placed in a drying box under a vacuum of 1.3 standard atmospheric pressure to constant weight, and the mountain carrot seed oil can be obtained; Carrot seed oil contains 25% fatty acids.

Abstract

The invention relates to the technical field of agriculture, in particular to a method for planting dendrobium officinale under a forest. The method is characterized by including the specific steps of selecting epiphytic culture trunks, arranging irrigation devices, preparing dendrobium officinale seedlings, and transplanting dendrobium officinale seedlings. By means of the method for planting dendrobium officinale under a forest, 360-degree dead-corner-free irrigation is achieved for planting dendrobium officinale under a forest, the effect of increasing the yield is achieved, the input cost of irrigation is reduced, and the waste of water resources is reduced; the method is simple and easy to implement and can increase the emergence rate, the survival rate and the polysaccharide content of dendrobium officinale and ensure a larger tiller number, so that the quality of dendrobium officinale is improved, and obtained dendrobium officinale has high economic value.

Description

【Technical field】 [0001] The invention relates to the field of agricultural technology, in particular to a method for planting dendrobium officinale under forests. 【Background technique】 [0002] Dendrobium officinale, also known as black knot grass, is the stem of the perennial epiphytic herb Dendrobium officinale in the genus Dendrobium orchidaceae. It is named for its iron-green skin and is a precious wild medicinal plant. Born on the semi-shady rocks in the mountains at an altitude of 1600 meters, it likes warm and humid climates and semi-shady and semi-yang environments, and is not cold-resistant. Generally, they can withstand low temperatures of -5°C. Dendrobium can be divided into dozens of species such as yellow grass, nobile, horsewhip, etc. Dendrobium candidum is the best product of Dendrobium. Dendrobium candidum has unique medicinal value. Its stems are used as medicine. According to the "Chinese Pharmacopoeia", Dendrobium has the effects of nourishing the stom...
